Bridges in Iowa

Romance fans worldwide make the pilgrimage to this group of historic covered bridges in rural Iowa.

At a mile long, the Fort Madison Bridge is the largest double-decker swing-span bridge in the world.

A half-mile long and three stories high, this bridge over the Des Moines River Valley mimics a descent into a mine shaft.

A warning to the weak-kneed: This narrow bridge does its swinging eight stories high.
